Victory Academy Co-Founder Tricia Hashbrook said the first break-in occurred in July. The cart holding the iPads was damaged, but no items were taken, she said.

In September, a thief used metal cutters to access the computers and steal two.

Hashbrook said the school installed a security system and re-keyed the building before the third break-in occurred last weekend. The school now has two remaining iPads.

Police are continuing an investigation, and believe the thief is likely an insider.

"Unless you had some inside knowledge... you wouldn't even know (the iPads) were there," Collinson said.

Victory Academy, located on Southwest Canyon Creek Road in north Wilsonville, was founded in 2009 with the goal of providing an integrated educational and therapeutic program for kids with learning differences. Twenty-nine students currently attend the school, and many of them rely on the iPad in the classroom, Hashbrook said.

"Technology has revolutionized learning for these students," she said. "A good percentage of these kids use them to communicate. They will type on their iPad in a program called Assistive Chat, and the iPad speaks for them. It's their voice."

The kids also use the computers to download books and access math programs, Hashbrook said.

"For our students, this is a really huge hit and a burden, and many of our students are feeling anxiety over this," she said. "They don't really get why somebody would be so immoral to keep doing this to them."
